The grey whitish mycelium of Colletotrichum capsici gradually developed from the second day in culture of isolates. In the tea plant, Colletotrichum exists as both a pathogen and an endophyte (Liu et al., 2015). taken from agar cultures in that greater than 97% of the spores produced on agar were uninucleate. This pathogen may perform as an excellent model for studying pathogenicity, from saprophyte to pathogen 15. The ITS region of PHBN0002 had a 95% similarity to the ITS of the epityped strain C. musae CBS116870 (Fig. conidia) is an asexual, nonmotile fungal spore that develops externally or is liberated from the cell that formed it. Pure cultures obtained by the here described procedure can be used for the investigation of morphological characteristics by employing microbiological and microscopic procedures, as well as to apply or develop . Origin and morphological traits of the selected Colletotrichum truncatum isolates used in this study Two hyphae from different Colletotricum individuals fuse together and produce a spore through sexual reproduction. Of the 84 Colletotrichum isolates collected from soybean petioles, 40 were C. incanum, indicating that this species may commonly occur. BIOLOGY. Culture colony characteristics Colletotrichum (sexual stage: Glomerella) is a genus of fungi that are symbionts to plants as endophytes (living within the plant) or phytopathogens.Many of the species in this genus are plant pathogens, but some species may have a mutualistic relationship with hosts. The fungus produces hyaline, one- celled, ovoid to oblong, slightly curved or dumbbell shaped conidia, 10-15 µm in length and 5-7 µm in width. C.-E. Conidia. Acervuli of C. truncatum on stem of soyabean. condition of spores of Colletotrichum spp. Conidiogenesis is the formation of asexual spores (conidia or conidiopspores). This is the first symptom to appear on plants, which are symptomless until the VN and R1 growth stage. Anthracnose disease caused by Colletotrichum gloeosporioides is a major cause of concern among farmers not only in India but around the world as it causes huge pre and post harvest looses to a number of fruit and vegetable crops. The crude enzyme from B. velezensis CE 100 exhibited chitinase, protease . Diseased tissues suspected of being caused by Colletotrichum were cut into 1- to 2-cm lengths, surface-disinfested, and placed on water agar. Based on cultural characteristics and spore morphology, isolates Arl-NW and 57RR resembled C. trifolii Bain & Essary and C. gloeosporioides (Penz.) The c ulture filtrate and bacterial lysate of XW2 were antagonistic against hyphal growth and spore germination. 49 The following morphological characteristics were evaluated: conidia morphology, and characteristics such as culture appearance, color and growth rate. Anthracnose. 2010). Distinctness in spore morphology and colony characteristics among the isolates resulted in morphological groups being identified that correlated with the Colletotrichum species regardless of the host species from which they were obtained . The average diameter of the inhibition zones of hyphal growth were 22.3 mm for the culture filtrate and 12.1 mm for the bacterial lysate. During the first stage sampled (stage 5: inflorescences development) a very low value of all the spore types was recorded. The disease causes highly damage by reducing plant stand, possesses characteristics typical Of melanin (2,4,5). The objectives of this study were to characterise this fungal pathogen, based on morphology, molecular characteristics and pathogenicity. 1.6 Colletotrichum . based on their cultural characteristics, mainly whitish, greyish, and creamish colour and cottony/velvety mycelia on the top side of the culture and greyish cream with concentric zonation on the reverse side. Recently, two unusual isolates of Colletotrichum (isolates Arl-NW and 57RR) were identified as highly virulent to specific cul-tivars of alfalfa with genes for resistance to anthracnose (14). B13 was purified by single spore isolation and incubated on PDA at 25°C under continuous fluorescent light, producing white to pale yellow colonies with dense aerial mycelia. Prabhakaran Nair, in The Agronomy and Economy of Important Tree Crops of the Developing World, 2010. Molecular characteristics of C. musae. The control consisted of suspensions of Colletotrichum conidia in sterile distilled water. The glomerulus is the perfect stage of Colletotrichum and belongs to the class Ascomycetes . produced spores which were straight with rounded end, ranging within 3.0-5.0m in width and 10.3-18.2min Table 4: Colletotrichum and Pestalotiopsis isolates with their After confirming the spores, the cultures were purified by single spore isolation technique. Keywords: Colletotrichum, single spore, morphological and cultural characteristics, perithecia, Gllomerella Introduction Colletotrichum are fungal pathogens that devastate crop plants. The pathogen continues to grow on the dead parts of the host tissues and perpetuates itself even in unfavorable conditions. Spores of the parent strain 104-T and 17 albino mutants were incubated on nitrocellulose membranes in the absence ( ) or in the presence Conventionally, Colletotrichum species identification was done by a variety of cultural and morphological characteristics growth rate, size of conidia, presence or absence of setae, sensitivity of fungicide, colony color etc 6,8,13,14.
